Beibut kindjal with early european blade ? Origin ?

[francantolin]

Hello dear members,
It was a long time I didn't post anything.
Here is an interesting long beibut dagger I found that I would like to show you:
large military type model but with horn handle and a ''15'' written on it.
A mix between europeans and east european-asian influences
Under the scabbard, an interesting blade, I hadn't seen it before I got it, a nice surprise !
It is very rusty but with an unusual very large yelman and a Passau wolf and the initials H and M and small crosses on both sides.
a very old blade ?
the tip- bouterolle also with the leather that goes over the leather sheath seems to me unusual with ''classics'' kindjal and reminds me 18th-19rh Prussian-Austrian short swords models.
Here some pictures
